        My ecoboost mustang is completely stock. Do I need anything else?

        • You shouldn't need anything else to install this JMS BoostMAX Performance Booster on your Ecoboost Mustang.

        Mounted everything under the dash . I want to make sure my JMS boost control is working proper. When I turn the engine on the green light is on and I have 2red lights flashing on and off . I have missed the instructions.

        • With the JMS BoostMAX Performance Booster installed you should have all 3 lights illuminated. The green light should remain on to show the unit is powered. The two red diagnostic LED's are used to display the settings. The rate at which the red LED's will vary in their state (slow blink, fast blink, solid) based on pedal position, and the setting for your remote boost knob. Seeing these blink will not be an indication of any issues.

        What fuel octane is compatible with this non-race version. I understand the race version requires 100 octane.

        • The JMS BoostMAX Performance Booster does not require a specific octane for proper performance.

            Be careful with this product

            Yes I probably would have given it a 5 star rating if it had told me that it only works with certain tunes. It doesn't not work with the Lund racing tune and if u have both installed it breaks your engine and messes up your air/fuel ratio

            Ecoboost to Ecobeast

            Really wakes up the little turbo, and when stacked with a JMS Pedalmax and a Bama tune, the car really turns into a beast. Accelerates like a 5.0, no kidding. Highly recommended

            Besting some of the best tuners on the market

            I have personally ran the BAMA X4 tune and this JMS BoostMAX booster. I have ran them together and separately. Lets talk about stand alone for each unit. BAMA X4: Great power gains and really keeps the car from falling on it's face past 4k RPM's. The torque is also a very nice addition worth mentioning. The launch and mid pull of the car is so much more smooth and the turbo lag is almost non-existent. JMS BoostMAX: This is a plug and play module that will transform your car without having to flash your ECU. My car runs (In my opinion) better with the JMS BoostMAX than with the BAMA X4 tune. The throttle response is better, the 0 - 60 times are better and top end speeds are higher. Now let me talk to you about them being stacked together. (Please Note and read below, this set up gives incredible gains in power and will need the following or the turbo/motor can be damaged) BAMA X4 and JMS BoostMAX stacked: This combination is absolutely amazing and you really have to be careful and make sure you are straight when you punch it, because it will literally make the back end come around on you (I've had the back end try to come around on me going 40MPH and punching it on a straight away). Upgrade of the BOV, Intercooler, intercooler piping, downpipe and catback exhaust is required to for this set up. It produces way to much power for the stock hardware and it will cause the turbo to overheat because it's not getting enough air flow in and out of the turbo. How do I know this? Because this happened to me and I thought the two just didn't work well together, but I was very wrong. My car was pushing so much boost and air, that the stock hardware couldn't handle it and after 3-4 hard pulls, it would throw an engine code saying the car is low on boost, because the car was automatically lowering the spark of the engine to keep it from damaging the car. When this happens, the car is set to 10PSI and it will throw an engine code telling you "Underboost Condition detected". I thought there was something wrong with stacking BAMA X4 and the JMS BoostMAX together. After many calls to BAMA, they sent me a RMA UPS Label to return the tuner. I had 30 days to return it and I knew I needed to upgrade my stock hardware anyway, so that's exactly what I did. All I can say is "WOW!". The turbo no longer over heats and the power increase blew my mind. Car is running around 26 PSI with both stacked together and the motor is producing 430 horsepower / 480lbs of torque. The car runs low 12s through the quarter mile and goes from 0 - 60 in 4.5 seconds (If you can launch it without spinning) It gives me a lot of happiness knowing this 4 banger is blowing V8's out the water on the street. The lower weight and high torque makes this car hard to out run 0 - 100. Top in, the V8's always take me, but who cares about top ends? And how does this car perform around curvy roads? well, let's just say a hellcat couldn't keep up with me. Car is too heavy and doesn't hug the curves like my little ecobeast! Final conclusion to everyone. Get this set up immediately if you have the funds to do so. My set up will cost you roughly $5000 with all parts and labor. Why not just buy the turbo upgrade kit for that price? Because with stock hardware, you wouldn't be able to handle that much power. My next step is to upgrade to a 55MM Turbo system, but for right now, I'm very happy with my little 4 banger. My mobs are as followed: Turbosmart 10psi Wastegate = $140 Turbosmart 30PSI Max recirculating BOV = $207 Roush Cold Air Intake = $380 Mishimoto Intercooler = $520 Mishimoto Intercooler Piping = $388 Mishimoto High Flow Catted Downpipe = $520 Mishimoto Oil Cooler = $535 Custom Flowmaster Catback exhaust = $600 JMS BoostMAX Controller = $310 BAMA X4 SCT Tuner = $400 Eibach Pro Series Lowering Springs = $230 Labor to install everything = $600 Total cost for everything minus shipping cost = $4830 Total cost with shipping included = $5015 Expensive? Maybe to some, but for the price to performance ratio for a car of this caliber, you can't touch it. Hope you enjoyed me talking about these two products and good luck to all you ecobeast owners!
